SEECIFCATION forming part of Letters Patent No. 709,719, dated September 23, 1902.

Application filed April 30,1902. Serial No. 105,365. (No model.)

To (tlf, whom it may concern.-

e it known that we, AGRICOLE PETER Mo- REsI and HENRY JOSEPH BEReERoN, citizens of the United States, residing at Jeanerette, in the parish of Iberia and State of Louisiana, have invented certain new and useful Improvements in Steam-Engines; and we do hereby declare the following to be afull, clear7 and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in oscillating steam-engines.

rl`he objects of said invention are to promote effectiveness of operation, to reduce proportionately the dimension ot' the piston-cylinder, and relatively increase the stroke of the piston, effecting economy of expense in the running of the engine. It also effects simplicity of construction and arrangement of the parts employed in securing the aforesaid ends.

The nature of said invention consists of the combination and construction'of the parts, substantially as hereinafter more fully disclosed, and specidcally pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment of our invention, Figures l and 2 are side elevations. Fig. 3 is a partially-horizontal section and plan view. Fig. 4 is a vertical transverse section taken on the line 0011; of Fig. 3. Fig. 5 is a horizontal section taken on the irregular line y 'y of Fig. 4. Figs. 6 and 7 are opposite detailed views of the ported side of the piston-cylinder and the correspondingly-ported seat for said cylinder. 4

It will be understood that We do not limit ourselves to details, as they may be changed at will without departing from the spirit of our invention and the same yet remain intact and be protected.

In carrying out our invention We mount in a suitable frame or support l na revolving piston steam-cylinder 2 and a balance or crank wheel 3, journaled in position and conuected up, as will be next described.

piston-cylinder of proportionately reduced dimension has laterally a planed preferably disk-like surface or face portion 4, having two Said ports 5 5a therethrough communicating with the piston-chamberatslightly-diagonal points out of the horizontal or vertical. Facing or fitti ug said planed disk-like surface 4 is a correspondingly-planed disk or washer l5, held steam-ti ght thereagainst by a nut and washer 7 7, engaging a trunnion or axis 8, integral with said cylinder, and passing centrally through said disk or washer, said n ut exerting pressure u pon said disk through said washers. Said disk (i is itself held or jammed against the support of frame l by means of suitablyheaded bolts 9, inserted through the latter and engagingscrew-lhreaded sockets in said! disk, washers Si preferably being inserted upon said bolts between their heads and said frame. Two pipes lO and l1, one connecting with a head or source of steam-supply and the other serving as an exhaust and passing through and supported in the frame l, communicate with the ports (ib oa in the disk G. Said piston-cyl inder has the rod lla of its piston l2, which projects beyond one head thereof, as usual, connected up with a crank or fly wheel 3, suitably journaled in the frame Las before stated. This connection is preferably effected by providing said wheel at its periphery with an integral or fixed lateral arm or projection 14, engaging at its free end a socket l1b at the outerend of said piston-rod, providing a loose joint at that point. Said piston-cylinder is hung or journaled out of alinement with the axial plane of the `Iiy or crank wheel 3, in the present instance above said axial plane, although it may be hung below said plane, if desired, allowing said cylinder to make a complete revolution during each stroke of the piston.

It is obvious that economy in fuel and .steam is obtained by this construction and arrangement of parts, providing for reducing the dimensions of the cylinder as compared to the ordinary engine-cylinder.

By a system of valves the action of the engine can be controlled, so as to be readily reversible, as required, for hoisting or other p urposcs requiring two motions or for driving the engine to the right or left.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
